In short
Your Stressy is a health and fitness app for Apple Watch and iPhone that turns sleep, heart rate variability and stress data into a single 0 to 100% reserve. It suits people who want a quick read on how much energy they have through the day, and a readiness check before hard training. One notable feature is a bedtime coach that shows the latest bedtime that still gives a full, 90% or 80% wake-up reserve.
Summary by Debuts, based on the App Store listing.About
Stressy turns what your Apple Watch already measures into one number: your reserve, from 0 to 100%.
Sleep fills it. Stress drains it. Calm slows it down. Glance at your wrist or your iPhone and you know how much you have left today.
YOUR MORNING STARTS WITH YOUR NIGHT Deep sleep refills your reserve fastest. Stressy reads how your heart and HRV recovered overnight against your own usual, so a short or restless night starts you lower and a good one starts you high.
THROUGH THE DAY Every five minutes, your heart is compared with your own calm. Stress drains the reserve in proportion to how stressed you are, calm slows the drain, and mindful minutes recharge it. Workouts and walks count as effort, never as stress.
SEE EXACTLY WHY Today shows your whole day in one curve, your stress every five minutes, every activity with what it cost or gave back, and Behind the number: where yesterday ended, last night's recovery, and where your reserve went since you woke up.
LOOK AHEAD • Readiness: whether today suits hard training, from your reserve, recovery, sleep and recent training. Plan a workout and see tomorrow's wake-up with and without it. • Bedtime coach: the latest bedtime that still wakes you at 100, 90 or 80%, on a Liquid Glass dial.
ON YOUR WRIST AND EVERY SCREEN The living tank on Apple Watch, complications and the Smart Stack, plus widgets for your Home Screen and Lock Screen, including today's stress in detail, as bars or as a flowing line.
DESIGNED FOR iOS 27 A living liquid tank, glass numbers that hold their own liquid, and Liquid Glass throughout. Light and dark appearance, Dynamic Type, VoiceOver and Reduce Motion.
PRIVATE BY DESIGN No account. No servers. No analytics. No ads. Your health data is read on your iPhone and Apple Watch and never leaves them. One price, no subscription.
WHAT YOU NEED An iPhone and an Apple Watch. Stressy reads sleep, heart rate, heart rate variability, resting heart rate, workouts, steps and mindful minutes from Apple Health, plus your age and sex for your heart rate zones. Wear your watch to sleep for the best results; your personal baseline settles in within about a week.
Stressy is a wellness app, not a medical device. Your reserve is an estimate to help you notice how sleep, stress and rest shape your day.
